Abstract
A dressing technology for separating high-grade rutile from beach sand ore includes such steps as gravitally dressing raw rutile concentrate with hydraulic shaker to separate rutile and heavy ore from light ore such as quartz sand, magnetic dressing with induction roller type magnetic separator to separate magnetic impurities such as ilmenite and monazite, heating non-magnetic ore to more than 60 deg.C, and high-voltage static dressing to obtain high-grade concentrate containing TiO2 (higher than 95%) and P (less than 0.02%). Its advantages includes high separation effect and recovery rate.
Description
The present invention relates to a kind of high grade rutile separation process, be specially adapted to from beach placer, sort the high-grade rutile.
Beach placer is by ilmenite, zircon, rutile, mineral compositions such as monazite, its dressing method generally is to utilize gravity treatment with ilmenite in beach placer hair ore deposit, zircon, thing enrichments such as monazite become rough concentrate, and then the rough concentrate oven dry that enrichment is become or dry, with hole sizer is the 0.2mm sieve, abandon oversize, and screenings carries out magnetic separation with disk-type magnetic separator, obtain the magnetic product ilmenite concentrate, non magnetic ore becomes concentrate with the gravity treatment enrichment again, after the concentrate that enrichment is become is dried or dried, carry out rutile concentrate and non-electrical product zircon ore concentrate that high tension separation obtains electrical product 87% again.Can only obtain the rutile concentrate of 90% left and right sides grade with above-mentioned technology, not satisfy the needs of producing senior welding material with the rutile of this grade.
The objective of the invention is provides a kind of good separation effect that has, rate of recovery height, the ore-dressing technique that can obtain the high-grade rutile of advantages such as remarkable in economical benefits in order to satisfy the needs of the senior welding material of production.
To achieve these goals, the present invention is by the following technical solutions:
A kind of high grade rutile separation process comprises gravity separation, dries, screening, magnetic separation, high tension separation, it is characterized in that:
A. the rutile rough concentrate that beach placer hair ore deposit is utilized gravity separation, dries, obtains after the magnetic separation makes rutile separate with a small amount of quartz light mineral with the cassiterite heavy mineral through the waterpower table concentration;
B. the concentrate with the waterpower table concentration dries the back with the magnetic separation of induction roll-type high intensity magnetic separator, isolates ilmenite, monazite magnetic impurity;
C. the non-magnetic product after the magnetic separation enters the board-like Separators and High Tension Separation feed hopper of static and is preheated to more than 60 ℃, carry out electric separation with the board-like Separators and High Tension Separation of static then, the optimum working parameter of electrostatic separator: operating voltage is 8～25KV, emission electronic cathode and guide plate spacing are 50～120mm, and angle is 20～40 ° between negative electrode and guide plate.
Owing to adopt above-mentioned ore-dressing technique, can obtain TiO
2〉=95%, P≤0.02% high-grade rutile concentrate has satisfied the needs of producing senior welding material, and the present invention has good separating effect, rate of recovery height, advantages such as remarkable in economical benefits.
Description of drawings
Fig. 1 is the high grade rutile separation process flow chart.
Fig. 2 is that the present invention is applied to beach placer and sorts the rutile process chart.
The present invention is further described as follows by reference to the accompanying drawings:
The present invention utilizes high-grade rutile and intergrowth rutile and associated mineral at minute differences such as proportion, electric conductivity, magnetic, adopt gravity treatment, high intensity magnetic separation and the high tension separation technique that combines, select the optimum working parameter of induction roll-type high intensity magnetic separator and the board-like Separators and High Tension Separation of static, make rutile and associated mineral effective separation, obtain TiO2〉=95% high-grade rutile concentrate.
From high grade rutile separation process shown in Figure 1, the rutile rough concentrate is that rutile and electrical close again nonmagnetic heavy mineral such as cassiterite, gold etc. are carried out effective separation with the purpose of waterpower table concentration, cleans mineral surfaces by water simultaneously and has created more favourable separation condition for next step adopts induction roll-type high intensity magnetic separator magnetic separation and the operation of the board-like Separators and High Tension Separation electric separation of static. Induction roll-type high intensity magnetic separator operating current is 8～15A, has the magnetic field intensity height, good separation effect, the characteristics such as production capacity is large; When the board-like Separators and High Tension Separation operating voltage of static is 8～25KV, electron emission negative electrode and guide plate spacing are 50～120mm, when angle is 20～40 ° between negative electrode and guide plate, can effectively the high-grade rutile be separated with the intergrowth rutile.
Embodiment
The rutile rough concentrate of beach placer is dried behind the waterpower table concentration, sieve for the 0.2mm sieve with hole sizer, oversize is abandoned, sieve raw material is down isolated magnetic mineral through the induction roll-type high intensity magnetic separator, induction roll-type high intensity magnetic separator operating current is controlled at 8～15A, non-magnetic product is preheated to more than 60 ℃ through feed hopper then, enter the board-like Separators and High Tension Separation electric separation of static, the board-like Separators and High Tension Separation operating voltage of static is controlled to be 8～25KV, emission electronic cathode and guide plate spacing are 50～120mm, angle is 20～40 ° between negative electrode and guide plate, isolates the weakly conducting mineral, promptly obtains TiO
